Frequently Asked Questions (FAQs)
Why does my image look grainy when I sharpen it?
Sharpening an image mathematically enhances edge contrast. However, if an image already contains digital noise (often caused by shooting in low light with a high ISO), the algorithm will enhance the noise as well. If your image looks overly grainy, reduce the intensity slider.
Does this tool reduce the resolution of my downloaded image?
No! The live interactive preview in your browser is scaled down slightly to ensure the slider responds instantly without lagging your computer. However, clicking "Apply & Download" runs the filter on your original, full-resolution file.
Can this tool fix severe motion blur?
While this tool is incredible for fixing soft focus, slight camera shake, and lens softness, it cannot magically recreate pixel data that was completely lost due to severe, fast-paced motion blur. It is a mathematical enhancement tool, not a generative AI.
